Presenting at the 2023 CFSA Sustainability Conference

This year’s Carolina Farm Steward Association’s Sustainability Conference was another great success. I was given the honor to share my passion about the mechanisms of biological fertility which I’ve taken a deep dive into over the last year after hearing Dr. James White speak about endophytic bacteria and the rhizophagy cycle at last years ACRES USA conference.

Presentation write up in the CFSA conference guide:

Mechanisms of Biological Fertility
Peter Brezny, Psycho Chicken Eco Farm

We hear all the time about how important soil health is, and it’s an easy concept to get behind because plants grow better with an active microbiological ecosystem to support them. But have you ever wondered why? Recent research has finally brought to light microbial interactions between plants and soil, and in this session, Peter breaks down the science of how fertilizers impact soil health and plants’ nutritional value, highlighting Dr. James White’s research on endophytic bacteria. He digs into how and why healthy bacteria impact plant nutrition and how that ultimately influences the nutritional value and flavor of the plants we grow.

Session Audience: Beginning to advanced growers, educators, and students interested in how recent research on biological fertility can be applied to any farming operation.

About the Speaker: Peter is a regenerative agriculture consultant, educator, and the founder of Psycho Chicken Eco Farm, an ecologically-minded vegetable farm and homestead in West Asheville, NC.

Here’s a link to the slides of my presentation:

Staying Current

The word around us is in a state of constant change. Understanding the world around us keeps us informed to make better decisions. Here’s my latest attempt to support trusted media outlets efforts to stay current.

Spoiler: Toxic substances are bad for our health. We should stop using them. The media can help us get there by letting everyone know how dangerous they actually are.

Subject: please do an update to your episode on autoimmune disease
To: <>

Dear Science weekly,

I’m a frequent listener to your show, contributor to the Guardian, Environmental Scientist, Biochemist, and most importantly, Farmer.

Your recent re-run episode on autoimmune disease could use an update. Your guest, James Lee, made no mention about the role of man made substances’ significant contribution to, and direct correlation with, the rise in autoimmune disease in ‘western’ lifestyle countries. 

In particular, the link between glyphosate (aka roundup) and autoimmunity has been studied for some time. Mechanisms of autoimmune disease initiation, tied directly to the glyphosate molecule’s documented incorporation into our proteins during DNA transcription, have been proposed.

When glyphosate is substituted for one of our essential amino acids, glycine, into protein structure, it frequently causes folding errors in the protein. These misfolded proteins are then recognized as foreign entities as they emerge from the cells in which they are made, triggering a response from our immune system.

So in this instance at least, contrary to what your guest proposed, we do know why our immune system turns on otherwise healthy cells in our bodies. I hope you will share this information with your followers in an update to this episode. Greater understanding of dangerous chemical substance incorporation into our and other animal proteins, will help spur legislation that could ultimately resolve this problem at its source (release of toxic substances), where we will make much more significant progress than we will by treating the symptoms (autoimmunity).

Please read:

“Toxic Legacy, how the weedkiller glyphosate is destroying our health and the environment”
–Dr. Stephanie Seneff

And perhaps do a follow up episode with Dr. Seneff to fill in the gaps left by your last guest on this issue of critical importance.

Like plastic pollution, forever chemicals, and toxic herbicides/pesticides/fertilizers, there exists a need to stop focusing on the symptoms, and solve these desperate issues at their source, by discontinuing use of substances incompatible with life on earth. Humanity has survived at high standards of living for generations long before the first plastic bottle, or drop of “crop protection” fluid, or non-stick pan was ever produced.

The invention of these things were for the benefit of mankind, but now that we have the ability to look back on their legacy, it’s time to turn the ship around toward a sustainable future, through the prohibition of substances incompatible with natural decomposition processes, and the promotion of new technologies compatible with our health, convenience, and environment.

Thank you for your time.

Peter Brezny

Encourage the NC Cooperative Extension

The NC Cooperative Extension, a valuable resource for NC Farmers is seeking feedback.

You can let them know what you think with their survey here (until April 30, 2020):

Of particular interest for me was the questions about their programs. Here’s what I had to say:

It’s not that you don’t have the programs.  It’s that the information in those programs are frequently based on research performed in the1950’s and ’60’s!

Restricting agents to only disseminate information from peer-reviewed research (frequently funded from dubious sources) is tying the hands of a critical resource–your agents.  This is a common issue nationwide.  While peer-reviewed research has it’s place, so to does the promotion of on-farm experimentation and exploration.  Sparking the imagination of farmers is far more productive and important than defining restrictive “Practices” for them to follow which may not work within their unique context.

NC has an opportunity to be a leader in supporting effective, non-toxic, regenerative farming practices. The “Peer Reviewed” research doesn’t necessarily exist in this field because in some instances, it is too young to have had the studies performed and peer reviewed.  Yet there are countless professional organizations with decades of research showing better yield, healthier produce, lower cost, and less dependence on fluctuating fertilizer and energy markets.  Rodale Institute, ACRES USA, Understanding Ag, the Savory Institute, the Xerces Society, and countless more all have extensive experience, research, and data spanning decades.  Incorporate this wealth of knowledge into your extension programs and stop tying the hands of your agents.

Now is the time for the NC State extension to eliminate ridiculous restrictions that require your intelligent agents to continue to recommend practices they know to degrade land, profit, health, and efficient use of resources.  

Business as usual isn’t working.  

Proscribing “Practices” has limited impact. Instead, of teach the observation of outcomes and adjusting your practices based on those outcomes. This is a much more effective management strategy if we are to make our farms resilient in these desperate and challenging times, created in large part by poor farm practices promoted by university extensions around the globe over the last 100 years.

Get ahead of this.  Be a leader.  Change the face of agriculture in NC as an example for the rest of the USA and the world to follow.  We can have the healthiest, most diverse, productive, and profitable farms in the country if managed properly.  

Don’t neglect to include farmland protection in your programs.  There are many people who will do this voluntarily if the resources they need to accomplish it are at their fingertips and they feel the support of the farming community behind them.  Without farms, we will be without food, regardless of how rich the stock brokers think they are. When the ‘bottom line’ becomes the health of our communities, we will all have much more to celebrate and be all the richer for it.

Why All the Pushback on Regenerative Agriculture?

As I’ve delved deeper into soil science and wholistic, regenerative agriculture, I’ve been surprised by the amount of resistance to the practice, and skepticism of the results put up by those in the environmental community, and the land grant university systems doing much of the formal ag research.

This week, I’ve come across two examples of academics criticizing globally admired regenerative agriculture-based farms (Brown’s Ranch, and White Oak Pastures) and neither had any evidence to back up their claims other than that they could find no peer-reviewed science to show what these operations were claiming could be done…yet they are doing it, and doing it well (both farms have built soil carbon, increased wildlife diversity, reduced inputs–in short, they have implemented regenerative systems that work with nature, rather than against it and are rewarded by lower input costs and higher quality products).

Andrew McGuire’s post from back in 2018 is one example. He’s an educator at one of my alma maters. From his bio ( you’d think he’d be a proponent of regenerative agriculture and interested in reproducing Gabe’s results, instead his article titled:
“Regenerative Agriculture: Solid Principles Extraordinary Claims.” ( appears to criticize the observed outcomes at Brown’s Ranch simply because he doesn’t see how they could be true. He attempts to justify his criticism with back of the envelope calculations based on antiquated, reductionist, and ultimately inaccurate assumptions, but doesn’t do a convincing job.

Thankfully there are now three years worth of insightful comments to help Andrew realize some of his blind spots. I hope he takes them to heart and focuses on supporting good outcomes, rather than tearing them down.

Here’s my response:


I’m so glad you took the time to comment on this article. There’s so much close minded, reductionist thinking in the world. Regenerative Agriculture has the power to turn around the slow motion train wreck of climate crisis we’re on right now. I’ve got a fancy master’s degree in Biochemistry myself (from WSU no less), and it took me years to break free of the arrogant, reductionist mindset that keeps us from seeing that there are forces at play in nature that we don’t yet fully comprehend–and that’s ok.

Just because the mechanism producing a factual, observed outcome isn’t understood, doesn’t mean it can’t work–which seems to be the crux of your argument Andrew. Either you believe Gabe’s results or you don’t. Your job as a scientist is prove your hypothesis with real data, not simply criticize based on assumptions and speculation–that’s just not helpful to anyone. If we all sat around waiting for peer reviewed science to catch up to the already realized benefits of reduced inputs, carbon sequestration, water filtering/conservation, reduced/eliminated ‘-cides’, increased biodiversity/wildlife that regenerative agriculture provides, it would simply be too late.

Ray, your observations above (that natural systems are dynamic, complex, and change from moment to moment, region to region) are spot on. We can’t investigate dynamic, living, ecosystems by looking at single component observed out of context and expect to gain understanding of the whole. Don’t get me wrong, I’ll be delighted when peer reviewed science catches up to modern regenerative agricultural practices, but there’s actually no need for a complete understanding of the mechanisms at play, as long as they are working and the outcomes can be accurately measured and reproduced.

Much of the universe from the human perspectives operates in a ‘black box’; we see the result, but we don’t know how it happened (here’s your link to quantum theory Andrew). Why can’t we accept that for Agriculture as well? Institutional science, funded by ‘big ag’ and the chemical companies that create dependence on their products which destroy the natural soil ecosystems that support agriculture production, fund a lot of this peer reviewed science. Want to get funded?… Ask the questions in your research that Big Ag wants you to answer.

I just can’t say it any better than you have Gabe so I’ll close by quoting you from above:

“Regenerative agriculture, unlike the current production model which you two expound, requires the power of observation and critical thinking. Andrew, you think things are meaningless unless they are peer reviewed. That is total nonsense! Most of the “research” coming out of our institutions today is meaningless to producers. It has led us into the industrial ag. mindset that is responsible for the demise of our natural resources and has played a major role in the decline of human health.”

Our planet is on fire. This is an emergency. We’ve got to work together using systems that produce results without degrading our environment, not attack one another because we don’t understand how those systems work.


There are literally thousands of ‘how to’ compost videos on youtube, and every other farm blog seems to have it’s own take on what you can or can’t, should or shouldn’t do… I find a lot of the ‘rules’ a bit of a storm in a teacup, so here’s our take.

Adding biochar to the pile before it’s final turn.

If you want to get high tech with it, knock your self out, check out the links below. If you can’t be bothered other than to dump kitchen scraps in a corner of your yard, that’s ok too (though you’ll be much happier if you put a few handfuls of leaves on top each time you take out your kitchen scraps). Either way you’re keeping organic matter out of the land fill and creating a biologically rich amendment for your garden or farm. As Nicole Masters says, ‘the elixir of life comes out of a worm’s butt’ so if you see worms in your pile, you’re doing something right.

The Johnson-Su Bioreactor

The best research we’ve found about developing fugal dominant compost so far has come out of Dr. David Johnson and his wife Hui-Chun Su who developed the ‘Johnson-Su Bioreactor’:

This passively aerated static pile involves very little work once setup and produces a great compost, almost regardless of what you put into the pile as long as you build it right, keep it moist, and add some worms after the thermophilic stage. Since discovering this method, we’re converting our larger, turned piles at the farm into static aerated piles to reduce fossil fuel use and tractor time, while producing a more fungal dominant compost, using a setup similar to what can be seen in this video:

Charles Dowding also has a great setup for his operation in England:

The bottom line is, everyone that produces an organic ‘waste’ stream ought to turn it into a resource by putting it in a compost pile. More and more, the important role of fungi in biological systems is being recognized so building your compost piles to encourage their development will serve you well. Different crops thrive with different fungal/bacterial ratios, here’s one deep dive, see what else you can find specific to your context on

“The molecular characteristics of compost affect plant growth,
arbuscular mycorrhizal fungi, and soil microbial
community composition”
